Adreno 420 (Snapdragon 805 - Galaxy Note 4) poor performance

Yeah, well, the problem is that sometimes we are too efficient on the CPU side. This can mean that the CPU itself isn't really all that busy, but the GPU is very busy. If the GPU driver's CPU usage isn't taken into account, or the scaling affects the GPU as it does the CPU, this can be an issue.

You can also try going into developer tools and setting the jit to off. It will eat a lot more CPU then... might be CPU limited, though.
